We perform a survey of DEnse GAs in MAssive star-forming regions in the Milky Way (DEGAMA) survey to study the distribution of dense gas in molecular clouds and its role in forming stars. DEGAMA focusses on a larger sample that is sensitive to all gas above a column density threshold of 10\(^{22}\)  cm\(^{-2}\)  with the goal of improving the understanding of how dense gas is formed and the relation between dense gas and star formation. The threshold column density of \(N_{\mathrm {H}_2}\sim 10^{22}\)  cm\(^{-2}\) , which might correspond to a volume
density of \(1\times 10^{4}\)  cm\(^{-3}\) , is chosen
because this gas directly builds massive star forming regions and forms lower mass stars (i.e., [1]}, [2]}).
